hash-cli

A simple command line tool to hash files.

Installation

$ npm install -g hash-cli

Usage

Usage: hash-cli [options]

  Options:

    -h, --help                             output usage information
    -V, --version                          output the version number
    -a, --algorithm [algo]                 Algorithm to hash with. Defaults to sha1
    -d, --directory [dir]                  Directory to hash
    -f, --files [file[,file[,file[...]]]]  Files to hash
    --createOutputFiles                    Create hash files: 'FILENAME.EXT.ALG'
    --list                                 List available algorithms
    --debug                                Debug on errors

Basic

$ hash-cli --algorithm sha1 --directory dir/to/hash --files file1,file2,file3

• This will output the sha1 hashes for file1, file2, and file3 in dir/to/hash
• Algorithm defaults to sha1 and accepts anything that require("crypto").createHash() accepts
• Directory defaults to process.cwd()
• Files defaults to every file in the specified or current directory

Hash every file in the directory

$ hash-cli -a md5

• This will create a .md5 file for each file in the directory

Force creation of hash files

$ hash-cli -a sha256 -f file1.txt --createOutputFiles

• Instead of outputting the shasum of file1.txt, this will create file1.txt.sha256

List available hashing algorithms

$ hash-cli --list

• This will list the result of require("crypto").getHashes()

Debugging

$ hash-cli [options] --debug

• If the debug option is supplied, the command will output a lot of debugging info. I'm not perfect.
